High-Clearance Design for Maximum Capability
The BDS 4.5" kit leverages a proven high-clearance crossmember design to increase ground clearance and deliver optimal strength. The system re-centers the front differential and corrects suspension geometry while preserving ride quality on highways and handling rough trails with ease. A full-width heavy-duty skid plate ensures essential drivetrain protection under the most demanding conditions.
Heavy-Duty Front-End Components
The front lift system includes high-arched 1/4-inch thick steel crossmembers, CNC-machined ductile iron steering knuckles, torsion bar drop brackets, and a multipiece differential relocation system. These work in harmony to maintain factory alignment angles and ensure proper axle positioning at the lifted ride height.
Included Front Suspension Components
The front kit includes all critical upgrades:
- High-clearance 1/4" crossmembers (front & rear)
- Heavy-duty multipiece differential relocation brackets
- Torsion bar drop brackets
- CNC-machined ductile iron steering knuckles
- Front skid plate for differential protection
- Sway bar drop brackets
- Bump stop extensions
- Brake line relocation brackets
- CV axle spacers
- All necessary installation hardware
Rear Suspension Options for Balanced Performance
In the rear, BDS offers two options to complete the lift and level your stance:
- Lift Blocks: Retains OE springs while replacing the factory block with a taller one to achieve proper rear height and maintain ride quality.
- Glide-Ride Leaf Springs: Full replacement rear leaf spring packs designed for maximum load capacity and ride comfort.
Both rear options include u-bolts, brake line relocation brackets, and a choice of performance-tuned NX2 Nitro or FOX 2.0 Performance Series shocks to match front ride dynamics.
